2019 Autumn Graduation Ceremony

September 25th is one of the great days at the Graduate School of Engineering, Osaka University. It is the day of Graduation Ceremony. This year, FIVE of our lab members graduated, two Master course students and three Doctor course students.

Big Congratulations to Dr. De Gracia L., Dr. Hector Ruiz V., Dr. Pinzon C., Mr. Azhan A. H. and Miss Phyo Myat Kyaw on your Graduation!!
We will always remember you as our lab. members and wish you all the best in your future!

Welcome to NAOE2 lab, Osaka University

We are one of the laboratories under the Naval Architecture and Ocean Material and Manufacturing Engineering (NAOE) department in Osaka University. We are conducting the research related to Fatigue strength analysis, Fracture Mechanics analysis, welding analysis, and corrosion prevention methods for ship and offshore structures.
